Zombie Squirrel Attack

You point and click to aim your gun and fire at the approaching zombies. Some zombies shoot back, so you frequently hit the spacebar to duck behind cover and avoid their attacks. As you clear waves, you unlock new weapons, switching between them with the number keys. The pace is steady, with the challenge coming from managing the different enemy types and your limited cover. It feels like a tense, methodical stand against a silly but persistent horde.
